What are you guys doing for longer bump stops on the front and rear of your trackers?

I did nothing up front, and used aluminum spacers in the rear between the rubber stop and it's mount. I removed the stock rear bumps, bought a few inchs of aluminum rod cut two spacers to length then drilled and tapped it. Threaded a stud into the body mount, thread the spacer on to the stud and the stock bump stop into the spacer.

Here is a commercially available spacer and what I patterned my DIY ones from, cheaper than shipping from the UK !!! LOL
